So for me in this situation you can buy your Bitcoin at day time and trade it at night when it adds
But it is very important to watch at it carefully.
I don't really agree if it really guarantees that you can make money when you buy at day time and sell it at night. The market is not supposed to go up when it's evening, you can barely see the chart and there's no evidence supporting on that because the price not always went up when it's evening. But I believe that it's good to trade in night time because there's huge volume.
Bitcoin is highly volatile, and that any time of day or night, its price will never be certain. So I don’t believe in this kind of analysis, as I only trade when I know that there are possible profits coming at the end of my trades. Regardless if it’s a day or night, as long as I’m in a mood to trade while seeing the market is favorable to trade, then I won’t hesitate to trade and risk some funds I reserved in trading.
It is indeed difficult to trade based on time, while price fluctuations occur erratically, therefore analysis is needed to find out support and resistance, usually that's when the price will react, either breaking through or reversing direction, so that we can read what will happen next, and after that we can determine our attitude. This is different from forex trading, where there will be certain hours for news that will occur, and whether the news will have a high impact or not.
